6 Claims.

'Ihe object of my invention is to provide a push and pull bar for doors, particularly intended for use on the doors of buildings to which the public has access, such as stores and shops.

It is an object of my invention to provide such a push and pull bar so constructed that it may be expanded or contracted for tting it to doors of diierent widths.

Still a further purpose is to provide such a bar adapted to carry advertising attractively displayed.

Another purpose of my invention is to provide such a push bar made of parts having such construction'that they can be readily produced by inexpensive die stamping methods and may then berreadily and easily assembled.

An additional purpose is to construct such parts in such manner that those elements adapted to carry the advertising can be readily removed and others substituted therefor, whereas the parts not carrying the advertising may be made standard for al1 widths of, doors and for use with different parts carrying advertising.

With these and other objects in view, my invention consists in the construction, arrangement and combination of the various parts of my push and pull bar for doors, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims and illustrated in the accompanying drawing, in which:

Figure 1 is a top or plan View of one form in which my invention may be embodied, parts being broken away.

Figure 2 is a front elevation of the push and pull bar illustrated in Figure 1.

Figure 3 is a vertical, 'detail, sectional view taken on the line 3-3 of Figure 2.

Figure 4 is a horizontal, detail, sectional view taken on the line 4-4 of Figure 2.

Figure 5 is a perspective view of my push and pull bar, parts being broken away.

Figure 6 is a front elevation of part of a modied form of device; and

Figure 7 is a vertical, sectional view taken on the line 'I-T of Figure 6.

For economy in manufacturing and for convenience in subsequent use, it is desirable that a push and pull bar of the kind under consideration should embody certain desirable features.

In the first place, it is desirable that the push bar be made in a standard construction, having parts capable of adjustment for adapting the push and pull bar to doors of different widths. 'Ihis saves the necessity for carrying a large variety of sizes in stock and reduces the cost of manufacture by reducing the number of dies which may have to be made.

It is also desirable that such a bar should carry advertising and that the part carrying the. advertising should be removable, so that another 5 similar part carrying different advertising may be substituted. This is in order that the user may get the maximum advertising benet Aout of his push and pull bar, and in order that he may change the advertising if that becomes desirable 10 without the necessity for throwing away the door bar'or without having to have it repainted or reenameled.v

'Ihese door bars are ordinarily made of metal and the advertising on the parts bearing it is 15 quite frequently in the form of stampings or raised letters. Furthermore by vmaking these parts carrying advertisinginterchangeable, it is possible to have factory production of such parts and to furnish them for interchange when that 20 is desirable.

In the drawing, I show two forms of bars. The form illustrated in Figures 1, 2, 3, 4 and 5 has a central section A and end sections B, telescopically connected therewith with the section A.

The intermediate section VA has an inner member ID and an outer member I I. Each of these members consists of a narrow elongated strip of metal, having its side edges bent to form flanges I2 extended toward each other and terminating 30 short of the ends of the strip. Y

The members I0 and I I carry the advertising, which may be formed by stamping raised letters, one of which for purposes of illustration is' illustrated at I3, and of course the whole outer face 35 of each such strip may be enameled in one color with the letters in another color or colors to make an attractive advertising display. The members I0 and Il, when placed together withl the edges of their iianges adjacent form a tubular box, substantially rectangular in cross section as perhaps best illustrated in Figure 3. The members I0 and I I have ribs |0a. and I Ia adjacent their edges having the flanges, for decoration, reinforcement and for cooperation with the binder strips -now to be described.

I provide edge binder strips I4 for each side edge of the so-called box. These binder strips are preferably made of brass or chromium plated metal, so as to give a better appearance to the completed device. They have the form of chan-f nel strips with their longitudinal edges curved around and in-turned toward each other, as indicated at Ilia (Figure 3). These curved flanges Ilia, form channels to receive the ribs IUwV-Ha 55 for rigidly holding the parts of the central member together.

These binder strips I4 are slipped over the boxlike device formed by the members I and |I at the side edges thereof, as illustrated in Figure 3 and also in Figures 4 and 5.

At each end of the push and pull bar is an end member B. The member B is preferably made in two parts, to-wit the outer part I5 and the inner part I6. The parts I5 and I6 are channel-shaped and their respective Widths are such that the anges |6a of the members I6 will slip just inside the flanges |5a of the member I5 as shown in Figure 3.

The end members B are slightly reduced in width toward their free ends as indicated at I'I and are inclined away from the plane of the central member in what I may call a rearwardly direction as indicated at I8, and terminate in flat, outwardly projecting plate-like members and 2| Thus, except at their extreme ends the members I5 and I6 form an elongated box-like member. l

For convenience'in assembly the finished device, the plates 2|) and 2| may be riveted together as indicated at 22. This holds them rather loosely together and makes the assembling job easier.

I may also say that the membersY I5 and I6 and theirflanges are so shaped that when the two members are placed together, their flanges |5a, |6a, preferably frictionally grip each other tight enough to hold the members together- The end members B are telescopically slid intoV the central member as illustrated for instance in Figure 5.

The outer parts I5 and I6 of each end member preferably have a series of holes 24. The parts fit so snugly that when the end members are slid into the central member they frictionally engage, but in order to more securely lock the endmembers tothe central member, I provide what might be called locking clips C, one for each end member. Y

Each locking clipcomprises a iiat plate-like part with an oiset linger 26 at one edge and with a rib 2T extending Aacross the edge opposite the` linger 26.4 At the ends of the rib 21, such rib is extended awayvfrom the plate 25 as indicated at 28, and each part 26 has a substantial flange 28a to fit over the side edge of the end member.

For locking the end members to the central member, these locking clips C are used. The offset tongue 26 is inserted through one of the holes 24. Y One of the clips is used on each side of each end member. The end member with the clip thereon is then forced telescopically into the central member. The rib portions 28 enter the channels at the edges` of the members I4 and tightly frictionally engage the inner walls thereof. rIhe flanges at the edges of the members I6 and II terminate short of the ends of said members to allow the entrance-of the anges 28a of the locking clips between the members I4 and the members I0 and II. i

By adjustingthe locking clips to different holes 24, the overall lengthof the bar may be varied as desired.

Before describing the modified form, I shall refer to some of the 'advantages of a device of this general construction.

If the storekeeper using the push and pull door bar desires to change the advertising on the bar, hecan removevthe bar from the door. The bar is fastened to the door 23 by means of screws 29 (Fig. 1) extended through holes 29 in the rivets 22 and the plates 20 and 2|. He can then pull out the end members and the locking clips and can readily remove the members I0 and II and substitute other members bearing different advertising. He may if he desires repaint the old plates I0 and Hand replace them in the assembly.

By adjusting the locking clips C in different positions on the end members B by inserting the tongues 26 into different holes 24, the overall length of the bar may be readily adapted to flt any width of door upon which it is to be used.

The whole device can be very quickly and easily assembled or taken apart. Each of the parts is itself a simple construction.

It is noticeable that advertising copy can be placed on both sides of the central member A (on the elements I0 and II) so that advertising matter can be seen from both Vsides-that isby persons entering or leaving through the door.

In-1igures 6 and 7, I have shown a modified form in which theend members B are the same as those ralready described. The locking clips C are omitted, and the central member indicated generally at D differs somewhat from the central member A. Y

In this ,modif-led' form, the central member comprisesY the channel-shaped inner and outer elements 30 and 3|. The parts are so formed that the flanges 30a of one of the elements, as the inner element 30, snugly t between the flanges 3Ia of the outer element 3| as clearly in- 35 dicated in Figure '7.

At each end of each member 30 and 3 IV is a projecting tongue or the like 32.

V The members 3D and 3| may be supplied with longitudinal ribs 33 for-reinforcing purposes.

The end members'B are telescopically associated with the central member D and are fastened thereto by means of bolts 34 extended through suitable holes in the tongues 32 and selectively received in any of the holes 24 in the end members. V

It will be observed that the second form of my door bar is substantially simpler than the first form described. Each form has certain advantages. In the second form, it is obvious that by removing the bolts 34, the ends may be taken out and either of, the members 30 or 3| may be repainted or removed and a similar element substituted.

It is obvious 'from the foregoing that the essential features of my invention may be embodied in different forms of bars, and it is my purpose to cover by my claims any modifications in details or changes in the arrangement and construction of the parts, which may be reasonably included within the scope of my invention and of my claims.
